Almost two decades and a few updated revisions, this book continues to be a bestseller and nearly on every mother-to-be's reading list. A very concise and expansive source of information not only on the changes your body will undergo but also what to look for when you're worried about your and your baby's health. Though this book covers practically everything under the pregnancy sun, it does not follow that every pregnant woman should follow it to the letter because as often mentioned in the book, a woman's symptoms, needs and situation is different. That said, this book is very helpful.
